What is a class D fire extinguisher?
I know that class A is for wood fire, class B for gasoline and grease fire, and class C for electrical fire. But what does a class D fire extinguisher do? Please help I got a quiz tomorrow on this stuff. I also know that a class ABC fire extinguisher can be used for all 3 different types of fire, so is it true that class D can be used for all types of fires? Or is there a specific kind?
D is for combustible metals. These are very hard to extinguish, once started, and may emit poisonous fumes. A “D” rating does not tell you whether the fire extinguisher can also be used on class A, B, or C fires; only the presence of the other symbols tells you that.
There are some tricks for remembering the classes. They have minor variations, but generally go like this:
A = Ash (wood fires)
B = Barrel (flammable liquids come in Barrels)
C = Current or Circuit (electrical fires)
D = Ding things (you can Ding metals), or
D = Do not fight, call the fire dept. (Due to poisonous fume potential)
